What are the common types of sensors

1、 According to the input physical quantities, it can be divided into displacement sensors, pressure sensors, speed sensors, temperature sensors, and gas sensors.
2、 According to the working principle, it can be divided into resistance type, inductance type, capacitance type, and potential type.
3、 According to the properties of the output signal, it can be divided into analog sensors and digital sensors. Analog sensors output analog signals, while digital sensors output digital signals
4、 According to the principle of energy conversion, it can be divided into active sensors and passive sensors. Active sensors convert non electrical quantities into electrical energy, such as electromotive force, charge based sensors, etc; Passive program sensors do not have an energy conversion effect, but only convert the measured non electrical quantity into electrical parameters, such as resistive, inductive, and capacitive glow sensors.
